25Tool Kit And Drill/Driver
How else are you going to put together all of your new IKEA furniture? They can't be made just by the enclosed hex wrenches we all hate. There's also nails and screws that need to be used. A put-together tool kit is a necessity, then, and it will have
all the tools you need, like a tape ruler, a hammer, a level, and screwdrivers. While you're at it, invest in a cordless drill/driver, like this long-lasting one from Bosch.
